Pellet stove exhaust pipe

[Coronacross]

Ok so I got my p-stove, I have to run the pipe through the fireplace , it will not only look better, but I cannot altar home (historical scocitey) however I've herd from 10 different people 20 diff ways to do it . Some say I can't go over 20ft of pipe others say run 3ft, others say I must go the full 30ft to the top , and yet also to save money I e herd to go 3-5ft with the good triple wall then go with stainless flex to the top??? Omg maybe I should have went with wood stove?? Can someone who really knows , please tell me how to do this in somewhat of a cheap yet safe way!!

So you got a pellet insert? Using the same Chimney that used to vent the fireplace? is that correct?

It's a straight up brick 30ft from floor to top with a cover 9in over the top.

With a pellet stove whatever you use has to go to the top. I run a pellet puppy in the basement into the 34 foot liner I used for a wood stove.

Reason being pellet stoves are positive pressure exhaust and you need it vented to the outdoors with no way for the exhaust to get into the living space. Four inch flex liner is available that will handle it.

Ok but after I Install the t-clean out pipe don't I have to run so many feet of the expensive 3in triple wall stuff then add flex or no??

And btw it's a free standing stove if that helps. Not an insert.

Did you have your chimney liner checked? If its good to go, you might just need to add stainless flex pipe after cleanout... your venting distances might require 4" pipe/liner if you have to go all the way to the top.

You can put the tee on and attach the liner to the tee. The guys here would have to suggest the appropriate tee for that. Or you could just run the liner from the stove adapter to the sky but you would have to disconnect the liner from the stove to clean it.

Do yourself a favor and go to the top with 4". I know it's expensive but it should be done right. I just replaced a 3" liner that went up about 18 feet in a 21 foot chimney, the amount of ash and soot on the block off plate was incredible! This time I ran a 4" exhaust and a 3" aluminum flex for fresh air all the way up. I have about $900 in liners and cap and am sleeping well now that I know it is done right!

Ok guys I'm getting it. And the chimmeney liner was checked b4 I moved in (no body lived here for years) the company said they all needed replaced in all 4 . That's why I went with pellet stove and thought by running pipe it wouldn't matter? Is this correct or am I making a fatal flaw

The chimmeney I'm using is straight from top to bottom (30ft) and is clean. As in free of objects

Straight out of the Harman P43 manual re Pellet Chimney installs...

*The chimney should be inspected and cleaned before installing your stove. If you discover that the chimney does not have a clay tile liner or has cracks or flaking of the tile liner you will need to install a stainless steel liner within the chimney. In most cases the inside diameter of this liner should be 4". Either flexible or rigid liner may be used for this purpose.

The chimney should be sealed at the damper using a steel plate. Kaowool, mineral wool or an equivalent non- combustible insulation is recommended to be installed on top of the sealing plate to reduce the possibility of condensation. The connector pipe should extend through the smoke chamber to the base or into the first flue tile. Seal pipe joints with silicone or aluminum tape in addition to the sealing system used by the manufacturer.

Be sure to design the venting so that it can be easily cleaned.

This guy has it right. Prob (maybe) do it yourself a bit cheaper? If you want to use different locations instead of the fireplace, you might be able to do a cheaper install... but a freestanding stove in an old fire place sounds worth the trouble!
